Seconding what @Alexr al'Petros posted. It is great to know what members of this community hold near and dear :) More people involved also means more friendships forged through common goals.
Volunteering is definitely my preferred method of being a SoA. But I also have the flexibility (self-employed) and love working with my hands. It's also small daily things: holding a door for someone, picking up random litter when able, educating others by example, etc.
What about you? Welcome...
